SELF-HEATED TOOL.`

Application filed April 6, 1923. Serial No. 630,286. K

To all whom t may concern.'

Be it known that FRED W. MILLER, a citizen of the United States,residing at Seymour, in the county of New Haven and State ofConnecticut, has invented certain new and useful Improvements inSelf-Heated Tools, of which the following is a specication.

This invention relates to a self heatedtool and has for its principalobject to provide a device which is adapted to 'heat a toolautomatically and is of such a construction as to enable the parts to beinterchangeable whereby a number of different tools may be used inconnection with the Vsame heating member.

Another important object of the invention is to provide a self heatedtool of the above mentioned character, which is of such a constructionas to enable the same to be used for various purposes and furthermore isadapted to be carried in the Ahands of the operator thereby renderingthe same a portable contrivance which renders it very useful and easilymanipulated.

Another' important object of the invention is to provide a self'heatedtool of the above mentioned character, which is provided with means forenabling the heating member to be attached to various kinds of tools andfurthermore is .provided with means for regulating the amount of heatnecessary to provide for proper operation of the tool carried lthereby.y

A still further object of the invention'is to provide a self heated toolof the above mentioned character, which is simple inconstructiom'inexpensive, strong, durable and further well adapted forthefpurpose for which it is designated.

@ther objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawings forming a part of the specification and inwhich like numerals designate like parts throughout the same Y,

Figure l is a longitudinal sectional view of my invention showing asoldering copper associated therewith.

Figure 2 is a transverse section taken on lines 2-2 of Fig. 1, lookingin the direction of the arrows.

Figure 3 is a sectional view taken on line 3-3 of Fig. 1.

Figure 4 is a side elevationof the sleeve associated with the burner.

Figure 5 is a side elevation of a tool used. 'i

inV surgery and which-is adapted for use with my heater.

Figure 6 is a brazin'g tool which isalso and for convenience maderelatively long in` proportion toits cross sectional dimension wherebythe same acts as -a handle for the device. The inner end of thereservoir 1 is connected toa hollowshank 2, andat thel outer end,l ofthe hollow shank 2 is mounted the burner designated generally bythenumeral 3. I'

The burner 3 comprises a tubularl body portion 4 and is provided with atubular neck 5 whereby the burner is carried by the shank 2 and theopposite end of the burner 3 is open.

The tubular body portion 4 of the burner 3 is furthermore provided witha centrally. located inwardly extending member 6 and this member 6extends inwardly from the neck portion 5 of the tubular body portion 4 asuitable distance as more clearly shown with the axial bore 7. The outerend of the axial bore 7 may be tapered and this pro-py vides what I terma combustion orifice.V `A

wick designated by the numeral `8 has one end thereof extending in thereservoir 1 and extends from the reservoir lthrough the hollow shank 2and into the tubular neck portion 5 of the tubular body portion 4 of theburner 3. This arrangement isV in Fig. l of the Vdrawings and is'provided more clearly shown in Fig. 1 of thefdrawings. The wick 8 asshown in thedrawings and whereby the fuel such as gasoline or the likewhich is contained in the .reservoir 1 is adapted to be conveyed fromthe reservoir into the burner 3 by means of theA wick which is also oftubular formation for the purpose hereinafter to. be more fullydescribed. Adapted to extend through the reser ioir l, and the wich 8and also through the neck portion' and the inwardly extendingcentrallyvlocated niernber 6 by'way of the Vaxial bore 7 ornied therein, is theneedle It will be noted ronillig. 1 ot valve V9. l the drawings that thetubular neck portion r5 ofthe burner 3 is provided with internal V12 forthe vpurpose of' receiving the 1 vneedle valve in its operativeposition.

It willu further be seen that theapertures provided in the body portion 4: will create a proper draft forthe proper facilitation and assuring the proper flame andexhaust gaseswill'pass through the apertures 25.

With a tool of the above mentioned character, it will be seen that thesimplicity of the same renders it very useful andefiicient for use invarious places and fordifferent kinds of work and is of such aconstruction as to enable the same to be easily handled without anydanger of injuring the operator and furthermore can be maintained at aminimum cost.

From the foregoing description of the construction of my improvedapparatus, it will be seen that I have provided a simple, inexpensiveand efiicient meansv for carrying out the objects of the invention, andwhile I have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be restorted to,without departure from the spirit or sacrificing any of the principlesof the invention.
